For glass that has to
stay looking like glass.
Pure nano-ceramic with remarkably low visible reflection. Close to invisible on the window, which is the point.
Sky at a glance
Sky is what you fit when the glass cannot look tinted — a heritage villa, a north-facing view you paid for, a room that is already dark. It still blocks 83% of infrared and 99.9% of UV.
What it does for the room
Nearly transparent
At 72.8% VLT the window keeps almost all its light. Visitors do not notice anything has been done to the glass.
Pure ceramic
No metal, so no reflective sheen and no interference with anything inside the building.
UV without the darkness
Same 99.9% UV rejection as the darkest films. Your floors and furniture stop fading without the room going dim.
The same view, at each shade
Official Zivent comparison. Pick by how much light you want to keep — the heat performance holds better across the range than you would expect.
VLT figures are indicative and can vary by 3–5% depending on measurement conditions and the glass they are applied to.

VLT visible light transmission — how much daylight the window keeps; lower is darker · IRR infrared rejection — the heat you feel through the glass · UVR UV rejection — what fades floors, curtains and furniture · TSER total solar energy rejection — all the sun's heat, the best single number · VLR int / ext visible light reflectance, inside face / outside face — a high exterior figure is what reads as a mirror from the street · Thickness the film itself; heat films are thin, safety films are not · SC shading coefficient — solar heat let through compared with plain glass; lower is better · SHGC solar heat gain coefficient — the share of solar heat that reaches the room; lower is better, and it is the figure a building specification asks for.
Where Sky goes
Heritage homes, rooms with a view worth keeping, north-facing glass, and anywhere a visible tint would be wrong.

Balance
A nano-carbon film on a metal base in a black brown tone. Low reflection, strong heat control, and the best visibility in the architectural range.

A platinum-tone reflective film with dual-sided reflection. The strongest solar control in the architectural range, and privacy that works in daylight.

Clear film that holds glass together if it breaks. A different job from heat control.
